Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] In the production process of lubricating oil, it is necessary to use a mixing tank to fully mix the lubricating oil, and it is also necessary to remove impurities from the mixed lubricating oil. In the existing technology, a filter screen or filter plate is usually simply set at the oil outlet of the mixing tank. However, if the filter hole size is large, the impurity removal effect is generally poor, and if the filter hole size is small, it is easy to get clogged.

[0034] Therefore, this utility model proposes a lubricating oil mixing tank with impurity removal function, which can effectively improve the above-mentioned problems.

[0035] The following description, with reference to the accompanying drawings, describes a lubricating oil mixing tank with a purification function according to an embodiment of the present invention.

[0036] Reference Figures 1 to 3 As shown, a lubricating oil mixing tank with impurity removal function according to an embodiment of the present invention includes: a tank body 100, a circulation component 200, and a filter component.

[0037] The tank body 100 internally defines a mixing chamber 101, and the mixing chamber 101 is provided with an oil extraction port 102 and an oil return port 103; the tank body 100 is also provided with a feed inlet 106 and a discharge port 107. The feed inlet 106 is used to add lubricating base oil and additives, and the discharge port 107 is used to discharge materials. In addition, the tank body 100 is also provided with a stirring mechanism 110 for stirring and mixing. The stirring mechanism 110 is prior art and will not be described in detail here.

[0038] The circulation assembly 200 is connected between the oil extraction port 102 and the oil return port 103. The circulation assembly 200 is used to extract lubricating oil from the mixing chamber 101 from the oil extraction port 102 and transport it to the oil return port 103 to circulate and transport the lubricating oil in the mixing chamber 101. The arrangement of the circulation assembly 200 allows the lubricating oil in the mixing chamber 101 to be mixed more thoroughly.

[0039] The filter assembly is connected to the circulation assembly 200. The filter assembly includes multiple filter sections 300, each with filter holes. Along the conveying direction of the circulation assembly 200, the multiple filter sections 300 are arranged sequentially, and the size of the filter holes in the multiple filter sections 300 decreases sequentially, so as to perform graded filtration of the lubricating oil conveyed by the circulation assembly 200. It can be understood that by setting up multiple filter sections 300, the impurities in the lubricating oil can be filtered in a graded manner from large to small, which can effectively prevent impurities from clogging the filter holes.

[0040] The lubricating oil mixing tank with impurity removal function of this utility model embodiment is equipped with a circulation component 200 to circulate and transport the lubricating oil in the mixing chamber 101, and multiple filter sections 300 to perform graded filtration of the lubricating oil transported by the circulation component 200. On the one hand, it can fully remove impurities from the lubricating oil in the mixing chamber 101 with good impurity removal effect. On the other hand, the multiple filter sections 300 filter impurities from large to small, which makes it less likely to cause blockage.

[0041] Based on the above embodiments, in some specific embodiments, the circulation component 200 includes a circulation pump 220, an oil extraction pipe 230 and an oil return pipe 240. The two ends of the oil extraction pipe 230 are respectively connected to the oil extraction port 102 and the input end of the circulation pump 220, and the two ends of the oil return pipe 240 are respectively connected to the output end of the circulation pump 220 and the oil return port 103.

[0042] Reference Figure 1 As shown, in some embodiments of this utility model, the oil extraction port 102 is located at the bottom of the tank 100, and the oil return port 103 is located at the top of the tank 100. In this way, the lubricating oil in the mixing chamber 101 can be fully circulated and transported, ensuring that the lubricating oil can be fully purified.

[0043] It is conceivable that, in order to simplify the structure, in this embodiment, a discharge pipe 108 is provided at the bottom of the tank 100, the bottom of the discharge pipe 108 forms a discharge port 107, an oil extraction port 102 is provided on the side wall of the discharge pipe 108, and a valve 109 is provided on the discharge pipe 108, the valve 109 being located below the oil extraction port 102.

[0044] Furthermore, a filter screen, filter plate, or filter cylinder can be installed on the oil outlet pipe below valve 109 to perform a second filtration of the lubricating oil during the discharge process, thereby improving the impurity removal effect.

[0045] Reference Figures 1 to 3 As shown, in some embodiments of this utility model, the filter section 300 defines an impurity chamber 301 inside, and the top opening of the impurity chamber 301 is configured to form an oil inlet 302. The filter hole is located on the side wall of the impurity chamber 301. During the process of the circulation component 200 conveying lubricating oil, the lubricating oil passes through the oil inlet 302, the impurity chamber 301, and the filter hole of the filter section 300 in sequence. That is, when the lubricating oil passes through the filter section 300, it enters the impurity chamber 301 of the filter section 300 from the upper side of the filter section 300. The advantage of this configuration is that the impurity chamber 301 with its opening facing upward can catch the impurities in the lubricating oil. When the filter section 300 is removed for cleaning, the filter section 300 can carry away the impurities, ensuring that the impurities will not remain in the circulation component 200 or return to the mixing chamber 101.

[0046] In some specific embodiments, the filter section 300 is configured as a square cylindrical structure with a closed bottom, but it can also be a circular cylindrical structure.

[0047] In some specific embodiments, the bottom wall of the impurity chamber 301 is not provided with filter holes to ensure the strength of the filter section 300.

[0048] Reference Figures 1 to 3 As shown, in some embodiments of this utility model, the oil return port 103 is located at the top of the tank body 100. The tank body 100 is provided with a vertically distributed mounting cylinder 104 at the top of the oil return port 103. Multiple filter parts 300 are detachably disposed in the mounting cylinder 104. The output end of the circulation component 200 is detachably connected to the top of the mounting cylinder 104. By setting the mounting cylinder 104 for installing multiple filter parts 300, it is convenient to disassemble and assemble the filter parts 300. When disassembling the filter parts 300, first separate the circulation component 200 from the mounting cylinder 104, and then remove each filter part 300 from top to bottom in sequence. The operation is convenient.

[0049] Based on the above embodiments, in some embodiments of this utility model, multiple filter sections 300 are sequentially sleeved from the inside to the outside, and there is a gap between two adjacent filter sections 300. By having multiple filter sections 300 sequentially sleeved from the inside to the outside, the vertical space occupied by multiple filter sections 300 in the mounting cylinder 104 can be reduced, and the vertical dimension of the mounting cylinder 104 can be avoided from being too large, thereby making it convenient for operators to assemble and disassemble the filter sections 300.

[0050] Reference Figure 2 and Figure 3As shown, in some embodiments of this utility model, the top end of the filter section 300 is provided with an outwardly protruding flange 303. The flange 303 is distributed circumferentially along the filter section 300. Among the multiple filter sections 300, the flange 303 of the outermost filter section 300 overlaps with the mounting cylinder 104. Among two adjacent filter sections 300, the flange 303 of the inner filter section 300 overlaps with the outer filter section 300. That is, multiple filter sections 300 overlap sequentially and are integrally overlapped on the mounting cylinder 104. The output end of the circulation component 200 is provided with a connecting part 210, that is, one end of the oil return pipe 240 is provided with a connecting part 210. The connecting part 210 is detachably connected to the top end of the mounting cylinder 104 and cooperates with the mounting cylinder 104 to clamp the flanges 303 of the multiple filter sections 300. The advantage of this arrangement is that the multiple filter sections 300 do not need to be directly connected to the mounting cylinder 104 or the circulation component 200 through fasteners or other components, making disassembly convenient.

[0051] Based on the above setup, when disassembling the filter section 300, first separate the connecting part 210 from the mounting cylinder 104, and then you can directly take out multiple filter sections 300 facing upwards. The steps are few and the operation is very convenient.

[0052] Obviously, the connecting part 210 and the mounting cylinder 104 can be detachably connected by bolts, making disassembly and assembly convenient.

[0053] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the upper end face of the mounting cylinder 104 is provided with a first recess 105, and the upper end face of the outer filter section 300 of two adjacent filter sections 300 is provided with a second recess 304. The first recess 105 and the second recess 304 are respectively used for the embedding of the flange 303, that is, the first recess 105 is used for the embedding of the flange 303 of the filter section 300 adjacent to it and located inside it, and the second recess 304 is used for the embedding of the flange 303 of the filter section 300 adjacent to it and located inside it. The flange 303 of the filter section 300 is embedded in the inner side. The bottom end of the connecting section 210 is provided with a connecting plate 211. The lower end surface of the connecting plate 211 is in contact with the upper end surface of all the flanges 303 and the upper end surface of the mounting cylinder 104, thereby cooperating with the mounting cylinder 104 to clamp multiple filter sections 300. In this embodiment, by setting the first sink 105 and the second sink 304, the filter section 300 can be limited in the horizontal direction, and the positioning and installation of the filter section 300 can be facilitated.

[0054] Understandably, in order to prevent lubricating oil leakage, a sealing ring 400 is provided between the lower end face of the connecting plate 211 and the upper end face of the mounting cylinder 104. The sealing ring 400 is located on the periphery of the flange 303 of the outermost filter part 300.

[0055] Reference Figure 3As shown, in some embodiments of this utility model, the filter section 300 is provided with handles 305 on opposite sides of the impurity chamber 301 to provide the operator with a better position for applying force, making it easier for the operator to lift the filter section 300 upwards.

[0056] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the connecting part 210 is provided with a vertically extending flow-retarding cylinder 212. The flow-retarding cylinder 212 is connected to the oil return pipe 240. The flow-retarding cylinder 212 is located directly above the innermost filter part 300. The inner side of the flow-retarding cylinder 212 defines a flow-retarding channel that meanders in the vertical direction. By setting the flow-retarding channel, the flow velocity of the lubricating oil before entering the innermost filter part 300 can be reduced, thereby reducing the impact on the filter part 300.

[0057] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, a plurality of buffer plates 213 are provided on the inner side of the flow-slowing cylinder 212. The plurality of buffer plates 213 are arranged vertically at intervals and staggered on the left and right sides of the flow-slowing cylinder 212. The buffer plate 213 on the left side is inclined to the right and downward, and the buffer plate 213 on the right side is inclined to the left and downward. The flow-slowing channel is formed by the plurality of buffer plates 213, which is simple and practical.

[0058] In some specific embodiments, the connecting plate 211 is disposed on the outer edge of the bottom end of the flow-retarding cylinder 212.
